Bit20

N.B. : This index fund is created using a BitShares smartcoin. All the information about these smartcoins is explained in the Bit20 section.Bit20 is available on the BitShares decentralized Exchange. If you want to operate a manual research, the asset name is : BTWTY

WHAT IS AN 'INDEX FUND' ?

An index fund is a type of mutual fund with a portfolio constructed to match or track the components of a market index, such as the Standard & Poor's 500 Index (S&P 500)."Indexing" is a passive form of fund management that has been successful in outperforming most actively managed mutual funds.

In other words, an index doesn't actually exist in a sense. Rather, it is an academic concept; an idea. Basically, it amounts to a person or a committee of people sitting down and coming up with a list of rules as to how to construct a portfolio of individual holdings because, in the end, the only thing you can actually do is invest in individual common stocks or bonds, presuming we're limiting our discussion to equity and fixed income markets.

COMPOSITION

Choosing how many cryptocurrencies would be included in the index

Including ten cryptocurrencies was our first approach for the index, however we thought that we were overlooking some interesting projects currently ranked in the 11th - 20th range, so even if the market capitalization of these coins is lower than the top 10 cryptocurrencies we felt they deserved to be part of the index since they have a lot of growth potential, we incorporated these coins with less weight on the Bit20 index and we left out coins below the top 20.

Ripple was intentionally excluded from the index since it constitutes a private and centralised institution, it is not considered a cryptocurrency and it is similar to a bank using the blockchain technology.

Percentage by coin

If we added the total market cap of the top 20 cryptocurrencies, we would obtain the total market capitalization of all of them. If we were to use the respective percentage of each cryptocurrency in the top 20 to define which part of the index they should have, we would end up with an index moving in parallel with Bitcoin which represents around 80% of this total market cap of all these coins.

Therefore, we opted for using the same system applied by traditional indexes which consist in having a maximum percentage by asset inside the index. So we proceeded by topping the first one, Bitcoin, at 10%. It left us with 90% to share on the remaining total market capitalization of the last 19 cryptocurrencies. Litecoin (july 2015) was the second biggest one and it also represented more than 10% of the total, so we capped it too. The same process was done to all of the 18 remaining cryptocurrencies, only the few biggest coins reach 10% and the vast majority have percentages going from 9% to 1%.

Initial value

Having the distribution well balanced was a precise task to do. To give a value to the index, we just had to arbitrary chose one. It could have been one dollar, the price of a cereal box or the national debt of a country. To keep things simple and elegant, we chose to gave to our index the price of an ounce of gold on his birthday date, the 21 of july 2015.

The average of several sources on the gold price created the initial value of Bit20 at: 1103.4733333333 USD.

With this value in mind and the percentages of each cryptocurrencies in the index, we could determine how much of each cryptocurrency would constitute the index.

REVISION

Once a month, the scripts involved in the composition of the index run a calibrating algorithm to redefine the coins that constitute the index. Without running this revision we would still have the same coins as they were in the top twenty on the 21th of july 2015. If we run this revision too often, the index is not stable. We consider once a month was enough time to have stability and also allow the index to evolve with the new cryptocurrencies in the top 20.

The revision consist in calculating the percentages of the top cryptocurrencies by market cap, just as we did upon the creation of the index. Once we have the new percentages, we determine how much each cryptocurrency will constitute the index NOT with the value of an ounce of gold BUT with the last value of the index in $.

Once the correction is done, the new composition smoothly replaces the one from the month before and no variation in the price is caused by the revision. We will notice that on each revision, some coins disappear from the index and new ones appear.

TECHNICAL DETAILS

BTWTY has been made in a way that even our team couldn't manipulate it after it has been launched. It is fully trustless and decentralized. It was necessary to reach that point of security. We want the index to be considered as a serious economic tool able to manipulate important funds.

There are two main key parts in the index structure.

As we've just seen, the algorithm creates the index itself. This algorithm calculates the weight ( % ) of each coin in the index.

The second key part is the mechanism producing the price and publishing it in the BitShares Blockchain.
The witnesses represent the highest representation of trust and decentralisation in the BitShares ecosystem. They have the code to produce the index price using the composition created by the first algorithm.
We had to provide the index composition for the witnesses but we couldn't risk to have it on a centralised server. This situation would have created a potential way to hack the index and change its composition and gaming the price. To solve that problem, we've used the BitShares Blockchain to store the index composition. Every month, we send the new composition in a standard transaction memo.

The witnesses read this memo and obtain the actual composition of the index. With that information, they can now build the index price using the price of each coins coming from several websites API.
